耐盐脱毛蛋白酶产生菌的研究──Ⅰ耐盐脱毛蛋白酶产生菌的筛选

Study on Salt -enduring,Unhairing Proteases Producing Strain Ⅰ. Isolation of the Salt - enduring Unhairing Strain

从已经开始掉毛的盐腌猪皮上筛选到一株可在８％盐浓度下生长的耐盐菌，该菌产生的蛋白酶具有较好的脱毛性能。经初步鉴定为芽孢杆菌，命名为ＢａｃｉｌｌｕｓｓｐＮｏ８１３。

Salt - enduring strain with a high unhairing protease activity has been isolated from thesalted - pig skins, named Bacillus sp. 813 by identity test. Expriment show that the strain cangrow in 8% NaCl and produces proteases, which are stable in pH7 ～ 11 and have high unhairing protease actVity.
